CVE-2026-98350
In the Linux kernel, the following vulnerability has been resolved: wifi: brcmfmac: cyw: pass PMKID to firmware if present Zero out auth_status on initialization.
Overview
CVE-2026-98350 is a known-severity vulnerability. It was published on October 6, 2026.
Technical description
In the Linux kernel, the following vulnerability has been resolved:
wifi: brcmfmac: cyw: pass PMKID to firmware if present
Zero out auth_status on initialization. Otherwise, garbage will
leak from the stack to the firmware (when ssid is less than 32 bytes
and/or when params->pmkid is set). Then, pass the params->pmkid to the
firmware (without it, the firmware caches a garbage PMKID on successful
authentication and denies a subsequent association request that includes
the PMKID).
